Title: Neue Alkylendiammonium-diclavulanat-Derivate, Verfahren zu deren Herstellung sowie deren Verwendung
Inventor: COPAR ANTON DR ING
IPC: A61P31/04
Filed: 1993-03-24
Abstract: Es wird ein neues Verfahren zur Herstellung von Clavulansäure und deren pharmazeutisch annehmbaren Salzen wie Kalium-clavulanat beschrieben. Demgemäss wird rohe Clavulansäure, die in der Form eines Extraktes in einem organischen Lösungsmittel wie Ethylacetat vorliegt, welcher Extrakt auf bekannte Weise nach der Fermentation mit einem Clavulansäure produzierenden Mikroorganismus erhalten wurde, mit substituierten Alkylendiaminen der Formel II <IMAGE> worin die Substituenten R1, R2, R3, R4 und R5 sowie n die im Anspruch 1 genannten Bedeutungen besitzen, z.B. mit N,N'-Diisopropylethylendiamin, zu neuen Alkylendiammonium-clavulanaten der Formel I <IMAGE> worin die Substituenten R1, R2, R3, R4 und R5 sowie n die im Anspruch 1 genannten Bedeutungen besitzen, z.B. zu N,N'-Diisopropylethylendiammonium-diclavulanat, umgesetzt. Die erhaltenen Verbindungen der Formel I werden gegebenenfalls isoliert und mti Alkalisalzen von Alkansäuren, z.B. mit Kalium-2-ethyl-hexanoat in Isopropanol, zu Kalium-clavulanat umgesetzt. Wegen der hemmenden Wirkung auf β-Lactamasen und einer signifikanten synergistischen Wirkung in Kombination mit β-Lactam-Antibiotika aus der Reihe der Penicilline und Cephalosporine sind die Clavulansäure und deren pharmazeutisch annehmbare Salze wertvolle Verbindungen zur Herstellung von galenischen Präparaten, die gegen durch zahlreiche Gram-positive und Gram-negative Mikroorganismen verursachte Infektionskrankheiten wirksam sind.

Abstract: A method for seeking the center of a data track recorded on a magnetic tape using a read head, having an accuracy which is not limited by the stepper mechanism which positions the read head relative to the tape, makes use of the discovery that the fundamental component of tape wander is independent of the tape cartridge vendor and the tape length, and therefore the tape wander can be averaged over an integral number of tape wander periods. In the method, the average output from a read head over an integral number of tape wander periods is found at the lower and upper edges of a data track. The read head output from the center of the track is then measured, and is used to calculate an output change versus head position when the read head is partially in the track. The output change versus head position is then used to scale the lower or upper edge position to a position which would result in an output equal to the output found for the opposite edge, and then the center of the track can be found by dividing the sum of one edge position plus the corrected position for the opposite edge by two.

Abstract: A method and apparatus for irrigating perforations in the surface of a perforated material (M) during surface treatment operations. The apparatus includes a three-layer substrate (100) of predetermined length including a first fluid-interactive layer (102), a second resilient layer (104), and a third rigidifying layer (103). In the method, the substrate (100) is placed beneath the perforated surface (M) to be treated with the perforated material (M) overlying the first layer (102). Thereafter, the surface treatment tool (T) is used to apply and remove pressure to and from the surface during performance of the surface treatment opertion. In this way, as the surface is treated, fluid applied to the surface during the operation is caused to pass back and forth to and from the first layer (102) and through the perforations to irrigate the perforations and thereby keep them from becoming clogged. In addition, the pressure applied to the surface by the tool (T) causes fluid held by the first layer (102) beneath the perforated surface to be expelled through the perforations in a region about the tool-surface interface, thereby flushing those perforations peripheral to the tool-surface interface.

Abstract: The invention assumes that the envelope of a decreasing alternating magnetic field for demagnetizing magnetic materials must be larger than can be achieved by conventional oscillating circuits. Accordingly, a gradually decreasing alternating magnetic field having a large decay factor is generated in an oscillating circuit (C1, L1, L2) in whose air-core coil (L1) the material is held. By specifically recharging the capacitor (C1) from a recharging capacitor (C2) by means of a power supply (LS2), the capacitor voltage (U1) is increased and the energy which is reduced by damping is resupplied synchronously with the oscillation process, so that the envelope E(t) of the alternating field is specifically enlarged and the duration of the decaying alternating magnetic field in the air-core coil (C1) is prolonged. <IMAGE>

Abstract: The present invention relates to an x-ray tomography apparatus (14) having x-ray tomography components (40,44,46-49) mounted for rotation around a patient. Such apparatuses are typically very massive resulting in high associated costs and restrictions in mobility. The present invention reduces the massiveness of these apparatuses by providing lighter power supply components (48,46) and a more versatile structural arrangement. X-ray apparatuses are thus provided which are more mobile and thereby more available for difficult to reach locations. In particular a wireless communication link is provided between the scanning means and relatively fixed data processing means.

Abstract: A film of weldable polymer material, for example polyethylene, which is to be used in earthwork and civil engineering is configured so as to be rough on both sides so as to improve its adhesion in slope regions. This is carried out by spraying on polymer particles in molten form and in the process welding them to the surface of the film. According to the invention, the average size and/or the average distance between the particles is variable on both sides. By this means, it is achieved that the film roughness, and therefore also the frictional adhesion of the film to the layers above and below it, is variable.

Abstract: An efficient billing system for value-added information. The present invention provides an efficient billing system in which an information provider can bill an information service fee in an efficient manner when the receiving device of a user receives toll information via radio communications, typically satellite (1) communications. The present invention essentially comprises a main unit (2) at a transmitter side having a host computer with a database for storing data of various types and a transmitter for radio communications, and a plurality of terminal units (3) for receiving said various types of data. Each data frame of various data types transmitted from the main unit has a data identification code identifying the corresponding data type. The terminal unit stores utilization status data which are processed and executed. The utilization status data singly or in combination with public utilities rate data are fed back to the main unit. Alternatively, information service fee is added onto the public utilities rate before they are billed.

Abstract: Biosynthetic production of 7-[1',2',6',-7',8',8a'(R)-hexahydro-2'(S),6'(R)-dimethyl-8'(S)-hydroxy -1'(S)-naphthyl]-3(R),5(R)-dihydroxyheptanoic acid, "triol acid", is accomplished by enzymatic hydrolysis of lovastatin acid or a salt thereof, by treating it with Clonostachys compactiuscula ATCC 38009 or ATCC 74178, or mutants thereof, or a cell-free extract derived therefrom, or a hydrolase derived therefrom. The triol acid and its lactone form are both inhibitors of HMG-CoA reductase and thus useful as anti-hypercholesterolemic agents, and may also serve as intermediates for preparation of other HMG-CoA reductase inhibitors. Also, in the synthesis of simvastatin by direct methylation of lovastatin, selective hydrolysis of residual lovastatin salt by treatment with Clonostachys compactiuscula ATCC 38009 or ATCC 74178 or mutants thereof or a cell-free extract derived therefrom, or a hydrolase derived therefrom yields the "triol" salt which can be easily separated from simvastatin.
